How to make phone as controller

Hey, I was reading somewhere that you can turn your android phone to a game controller. The thing is i want to connect one smartphone to another and play some psp game on second device. Is there any app that i can use to do that? Both phones are rooted.

Well, you have heard the correct news that is feasible it can be done ! What you are going need is application like wanderplayer, BT controller Lite etc... theses apps are available over the PlayStore for free an can be used to turn your android device into a game controller for playing games.
